    Works; or, within a display generated by the Derivative Works,
    if and wherever such third-party notices normally appear. The
    contents of the NOTICE file are for informational purposes only
    and do not modify the License. You may add Your own attribution
    notices within Derivative Works that You distribute, alongside

  Trademarks</a></strong>. This License does not grant permission
  to use the trade names, trademarks, service marks, or product
  names of the Licensor, except as required for reasonable and
  customary use in describing the origin of the Work and
  reproducing the content of the NOTICE file.</p>
  <p><strong><a name="no-warranty" id="no-warranty">7. Disclaimer

  implied, including, without limitation, any warranties or
  conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or
  FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for
  determining the appropriateness of using or redistributing the
  Work and assume any risks associated with Your exercise of
  permissions under this License.</p>

  consistent with this License. However, in accepting such
  obligations, You may act only on Your own behalf and on Your sole
  responsibility, not on behalf of any other Contributor, and only
  if You agree to indemnify, defend, and hold each Contributor
  harmless for any liability incurred by, or claims asserted
  against, such Contributor by reason of your accepting any such
  warranty or additional liability.</p>
